Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475054, here are decompositions:

73 + 31474981 = 31475054
181 + 31474873 = 31475054
271 + 31474783 = 31475054
277 + 31474777 = 31475054
307 + 31474747 = 31475054
367 + 31474687 = 31475054
631 + 31474423 = 31475054
691 + 31474363 = 31475054

Showing the first eight; more decompositions exist.
